In doing so, Oracle has bought its way into one of the OSS sector's emerging niches: network planning and optimization, which is likely to become increasingly important as carriers seek to sweat their existing assets (ewww!) while planning new IP network rollouts.

Netsure is a six-year-old software firm based in Dublin that is focused on two areas of carrier back-office operations: helping operators to manage their network capacity and to identify and plan expansion requirements; and managing the integrity of the data that carriers hold on their networks (a process known as data discovery and reconciliation).

It's not a big company, but neither Netsure nor Oracle will talk about how many staff it has (though it's believed to have about 20 employees), the Irish company's revenues, the acquisition price, or the size of Netsure's customer list.

The company has, however, named three of its customers -- Irish incumbent eir , Cable and Wireless plc (NYSE: CWP), and a part of the Vodafone Group plc (NYSE: VOD) empire -- and also claims to have a "major North American operator" using its Netsure Active Network Optimisation software suite.

Oracle's biggest leap into the OSS space so far has been the acquisition of MetaSolv, which specializes in network provisioning, service activation, and inventory management. And, according to Netsure CEO Barry Murphy, it was Netsure's work alongside MetaSolv that brought it to the attention of Oracle's Communications Global Business Unit team. "From the moment we spoke with them they could see there were synergies" with the MetaSolv capabilities Oracle had already acquired.

That's because Netsure's software works alongside, and uses information from, standard OSS systems. Its data integrity tool performs network audits and matches the resulting data with information held by the carrier's incumbent inventory management system to identify any discrepancies, which can then be fixed.

The network planning software uses data held by financial and OSS systems, mainly the inventory management system, to identify where the network is being underused, where network capacity can be freed up, and, using information from a carrier's marketing team, to predict how much capacity is needed to be able to deliver new services and to predict where network capacity might run out so that upgrades can be planned.

That process is becoming more important as carriers increasingly seek to make best use of their resources. "We're helping carriers to become lean operators," says Murphy.

In addition, carriers are using the planning tools to determine how much spare capacity they have when planning to bid for wholesale capacity contracts.

Murphy claims this focus on existing rather than greenfield networks, and the ability to build capacity planning models based on marketing information, sets it apart from other network planning specialists such as VPIsystems Inc. , Opnet Technologies Inc. (Nasdaq: OPNT), and Wandl Inc .

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
